The use of a dispenser at the office is not as frequent as at home, because it is only used during working hours or at certain times. The use of dispensers must be in accordance with established health standards, so the quality of water produced by the dispensers must also be hygienic and free of germs or bacteria. Generally, water dispensers are operated for 24 hours, meaning that the dispensers use up a lot of electrical energy. In addition, the use of dispensers must also comply with established health standards, so the quality of the water produced by the dispensers must also be hygienic and free of germs or bacteria. Meanwhile the quality of the water produced by the device cannot be monitored. To overcome this problem, a study was conducted by designing a hygienic and energy efficient water dispenser design by applying a forward scheduling approach. The design is carried out through several components, namely ultraviolet (UV), dispenser heaters, Arduino Uno sensors, DS18B20 sensors, HC SR-04 sensors, DC pumps, 2 relays, and RTCDS1307. The results of this study indicate that the dispenser heating system can work based on a set schedule by applying an advanced scheduling approach referring to the RTC DS1307 time reading. The UV lamp can be lit for 10 minutes to sterilize the main container of the dispenser with an estimated suppression of E. Coli bacteria about 87.5 colonies / minute. This system is able to suppress the growth of bacteria about 875 colonies for once lighting. This system can control the quality of water that is safe for consumption and saves electricity energy up to 79.87 kWh per month.
